Yan'an is a long and narrow city in a Y shape sandwiched by three mountain ranges.
The surrounding mountains are densely covered with undulating hills and ravines, and there is a river running through the city in the middle.
There is no point in defending the city in such terrain.
Therefore, Wu Sangui dispersed his troops on the surrounding mountains and guarded the Yanhe River.
Despite being abandoned, Wu Sangui still remembers his duties.
He wanted to hold off Liang Yue's army and buy time for Azig to retreat eastward.
Liang Yue knew what Yan'an was like better than Wu Sangui.
The battle was about to break out, and the two sides began to compete for one mountain after another.
Neither side wanted to go down into the river valley to avoid being condescended to by the other side.
However, the terrain above the mountains is narrow, and too many troops cannot be deployed, which makes the entire battlefield very scattered.
Liang Yue's advantage over Wu Sangui was that he still had a few remaining artillery pieces on hand.
In the past, when large armies fought, the few remaining artillery pieces were insignificant. But here, it became the key factor in determining victory or defeat.
After all, the terrain on the top of the mountain is narrow, and it only takes a few shots to cover it completely.
The Qing army did not have time to build complete fortifications on it, so it could not block the artillery bombardment at all.
In addition, the combat effectiveness of the Liang army was already stronger than that of the Manchu and Han armies, and the battle situation was somewhat unbalanced from the beginning.
Wu Sangui lived like a year, wishing that the ten days would pass quickly.
As long as he survives ten days, he can escape.
But when a person is at the end of his life, the crisis will only become more severe.
The biggest problem before him was running out of food.
The troops under his command are not incapable of fighting.
Although the number is not as good as the Liang Army, the weapons are not as good as the Liang Army, and the combat effectiveness is slightly worse. But if it lasts for a while, there is still no problem.
But if you are hungry, no matter how brave the warrior is, you will not be able to exert your fighting power.
By the afternoon of the next day, the tired and hungry Qing army could no longer hold on and lost seven mountains in one breath.
Wu Sangui had no choice but to retreat eastward along the Yanhe River.
How could Liang Yue let him go?
The army pursued them step by step and held them tightly.
Along the way, countless people fell in bloody battles between the two sides.
The flowing blood and the Yan River converged, dyeing the entire river red.
Wu Sangui had no other choice. He could only hope that Azige would leave him something to fill his stomach when he retreated to Yanchang County.

At the same time, Jian Zongan led the Sixth Division into Taiyuan City.
Niexai led 30,000 Qing troops to stand ready and blocked the way of the Sixth Division going north.
However, after getting the reconnaissance results, Jian Zongan even suspected that he had made a mistake.
"Niksey really gathered all his troops in the city? There were no arrangements on the top of the mountains on both sides?"
The reconnaissance company commander felt insulted when he heard such questions.
"Commander, this is what I saw with my own eyes. It is absolutely correct. There are really no Qing troops on the top of the mountains on both sides."
Deputy division commander Zhang Tao stood on the sidelines and marveled.
"Nie Kesai is not a famous general of the Qing army. How can he be so confused? How can he defend Taiyuan without guarding the mountains on both sides?"
The generals of the Sixth Division were all puzzled.
As for how to attack Taiyuan, Zuo Mengeng had already received detailed instructions from the Sixth Division when they were marching.
As a military master, Zuo Mengeng certainly knew the city of Taiyuan very well.
How Xu Shuai defeated Taiyuan is a classic example that every soldier needs to study carefully.
So he taught the Sixth Division ready-made examples.
As a result, when faced with the actual situation, everyone in the Sixth Division discovered that their original expectations were all in vain.
The Qing army completely emptied the mountains on both sides and only guarded the city, assuming a posture of being passively beaten.
Jian Zongan and others gathered together to discuss for a long time, but they couldn't figure out what kind of evil moth Niksai was playing.
In fact, the truth is straightforward and not complicated.
It is entirely due to the bias in the understanding of war between the two sides.
It’s not that Nikosi didn’t know the importance of the mountains on both sides.
Once occupied by the National Defense Forces, with a commanding position and suppressed firepower, it will be extremely difficult to defend the city.
But there was nothing he could do.
Because he didn't have any long-range weapons at hand.
Just relying on swords, guns, swords and halberds cannot reach far. Even if they occupied the mountains on both sides, they would not be able to provide any support to the city.
Once the National Defense Forces attacked the city from the south, the soldiers and horses he deployed on the tops of the mountains on both sides were purely for show.
He only has less than 30,000 people on hand in total. If he wants to assign them to guard the mountains on both sides, the number of troops defending the city will be too sparse.
There was no way to stop the frontal assault of the National Defense Forces.
In this case, we have to give up the mountains on both sides and only defend the city.
Although he will be beaten passively, the situation is difficult. But his mission is not to show off with the Sixth Division, but to buy time for Duduo.
If you can hold on for a moment longer, it is a moment. The outcome is not important.
This approach, which went against military common sense, left the Sixth Division a little confused.
However, it was an established plan to conquer Taiyuan, pursue Duduo, and form a two-sided attack with the Ninth Division, and Jian Zongan did not dare to delay.
Since the Qing army surrendered all the commanding heights, he was not polite and immediately sent troops to seize it.
One day later, Taiyuan City was surrounded on three sides.
From the high point, the city's defenses can be seen almost at a glance.
The artillerymen of the Sixth Division were too comfortable.
Under the guidance of the commanding heights, precise concentrated attacks were carried out towards the defense points in the city.
Amidst the continuous sound of artillery fire, Neksai's painstaking arrangements were dismantled one by one, and a large number of Qing troops were blown up alive.
Hiding in the dark, watching the city wall being baptized over and over again and beginning to crumble, Niksai wanted to cry without tears.
When they first fought against the Ming Dynasty, the firearms of the Ming army were already enviable to them. After they were captured, they were all regarded as treasures.
I feel that this kind of firearm is the most powerful in the world.
After they mastered how to use this kind of firearm, they felt that they had no rival in the world.
Why did God let the empire appear?
Why are the weapons of the Wehrmacht so terrifying?
This completely subverted their understanding of war and weapons.
Is there anyone who bullies people like this?
Jian Zongan couldn't hear his voice.
If you hear it, it will only get worse.
I have weapons and technical advantages, so I don’t use them. It’s not a stick.
The National Defense Forces not only poured firepower into the city from the plains to the south, but also used mortars and rocket launchers to attack the Qing army from the tops of mountains on both sides.
At noon, the mist dissipated, the sun shone brightly, and something appeared that completely broke the Qing army's heart.
"what is that?"
Amidst the shouts of countless Qing troops as if they were seeing ghosts, dozens of hot air balloons rose into the sky and slowly floated over Taiyuan City.
Niksai was stunned and didn't even notice that the knife in his hand fell.
He was so frightened that he... pooped his pants!
